Product details
Overview
TLE6263GNUMA1 from Infineon Technologies is a monolithic automotive System Basis Chip integrating a fault-tolerant low-speed CAN transceiver (up to 125 kBaud), 5V low-dropout regulator (LDO), high-side switch, window watchdog with fail-safe output, and SPI interface - all in a PG-DSO-28-27 package. It serves as central power management and communication interface in body control modules for wake-up event handling, bus supervision, and cyclic external circuit supply.
For engineers reviewing the TLE6263GNUMA1 datasheet, TLE6263GNUMA1 pinout, TLE6263GNUMA1 application, or TLE6263GNUMA1 equivalent, key selection considerations include its integrated LS-CAN transceiver compliance, VCC early-warning capability, HS-switch current rating, SPI-configurable operation modes (normal/receive-only/Vbat-standby/sleep), and AEC-Q100 qualification for under-hood environments.
Technical Context
The device implements a differential LS-CAN physical layer with CANH/CANL termination control via RTL/RTH pins and supports dominant/recessive bus state detection through TxD/RxD logic-level translation. Its internal 5V LDO delivers up to 150 mA with tight regulation (±2% over load/temperature) and integrates VCC early-warning and VINT sense comparator inputs for system-level voltage supervision.
Four SPI-configurable operation modes - normal, receive-only, Vbat-standby, and sleep - are managed via NSTB/ENT bits; the window watchdog asserts FSO low on timeout or under-current, while two edge-sensitive wake-up inputs (WK1/WK2) trigger INT and support cyclic sensing in sleep mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CAN Data Rate | Up to 125 kBaud - supports body electronics communication without requiring external timing components |
| LDO Output | 5 V ±2%, 150 mA - powers MCU and peripherals directly; requires ≥100 nF CQ capacitor at VCC |
| HS-Switch Current | Typ. 120 mA, max 250 mA - drives external wake-up circuitry or sensors; controlled via SPI or cyclic sense |
| Watchdog Type | Window watchdog with fail-safe open-drain FSO output - asserts low on timeout or VCC under-current |

Applications
| Body Control Module (BCM) | Door Module |
|---|---|
Use Scenario: Centralized control of door locks, windows, mirrors, and interior lighting in modern vehicles. IC Role / Device Role / Timing Role: Provides regulated 5V power, LS-CAN communication, and wake-up capability for distributed nodes.

Use Scenario: Controls sunroof motor, ambient lighting, and rain sensor integration in roof console assemblies. IC Role / Device Role / Timing Role: Supplies 5V to MCU and sensors; monitors VCC/VINT for early fault detection; interfaces via LS-CAN. Use Value: VINT sense comparator allows custom voltage monitoring (e.g., sunroof motor supply) without external comparators. | Use Scenario: Manages seat position memory, heating elements, and occupancy detection in premium seating systems. IC Role / Device Role / Timing Role: Delivers fail-safe power and communication; uses FSO to disable heaters on watchdog timeout or overtemperature. Use Value: Window watchdog with fail-safe output ensures heater cutoff within defined time window upon MCU hang. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive system basis chip applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33903DWBR2 | Includes LIN transceiver instead of LS-CAN; lower LDO current (100 mA); no cyclic sense feature | Better suited for LIN-based body nodes; lacks CAN bus support and HS-switch auto-cycling | Select when LIN interface suffices and CAN is not required; verify thermal design for 100 mA LDO |
| TLF35584QVVS1 | Higher integration: dual LDOs (5V/3.3V), ASIL-B safety features, CAN FD support; larger QFN-48 package | Targets ADAS and safety-critical domains; overqualified for basic body applications | Choose only if functional safety (ISO 26262) or CAN FD bandwidth is mandatory; increases cost and PCB area |
Compared with MC33903DWBR2 and TLF35584QVVS1, TLE6263GNUMA1 uniquely balances LS-CAN integration, cyclic HS-switch control, and compact DSO-28 packaging - making it optimal for cost-sensitive, CAN-based body electronics where AEC-Q100 Grade 0 and thermal robustness are essential.

FAQ
What is the maximum allowable input voltage on the VS pin?
The VS pin accepts a wide input range from 5.5 V to 28 V, supporting direct connection to automotive battery rails including cold-crank conditions down to 5.5 V. Operation below 5.5 V disables the LDO and may cause RO assertion; sustained VS < 4.5 V triggers undervoltage reset.
How does the cyclic sense function operate in sleep mode?
In sleep mode, the cyclic sense function periodically activates the OUTHS high-side switch (or samples WK1/WK2) at intervals set via SPI register IBit4, enabling autonomous wake-up source monitoring without MCU intervention. Each cycle lasts 64 ms, and the feature must be explicitly enabled via SPI configuration.
Can the TLE6263GNUMA1 be used with a standard high-speed CAN controller?
No - the TLE6263GNUMA1 implements a fault-tolerant low-speed (LS-CAN) transceiver compliant with ISO 11898-3, intended for wiring harness segments tolerant of bus faults. It is incompatible with high-speed CAN (ISO 11898-2) controllers due to different voltage thresholds, data rate limits (max 125 kBaud), and termination architecture.
What external components are mandatory for stable LDO operation?
A minimum 100 nF ceramic capacitor (X7R or better) must be placed between VCC and GND, located ≤3 mm from the IC. Additionally, a ≥100 nF capacitor is required between VCI and GND for internal supply stabilization, and a 100 nF capacitor must be placed directly between VS and GND near Pin 15 to suppress supply noise.
